  • Injector assembly employing compressed gas and a mechanical brake for presenting an intraocular lens to a patient
    Patent number: 11701222
    Abstract: An intraocular lens (IOL) injector is configured for single hand operation and employs a compressed gas to provide a motive force to present an IOL to a surgical site. The IOL injector includes a mechanical brake coupled to a plunger to preclude translation of an IOL absent operator input. The mechanical brake provides for selectively varying the speed and translation of the plunger, and hence IOL during presentation of the IOL to a patient. The IOL injector can also include at least a first stop, which halts movement of the plunger at a predetermined position. The at least first stop is then moved to a passing position, thereby allowing further operator controlled translation of the plunger to present the IOL to the surgical site.

  • INTRAOCULAR LENS INJECTOR ASSEMBLY HAVING SHUTTLE ASSEMBLY RETAINING INTRAOCULAR LENS IN STORAGE VIAL AND OPERABLY PRESENTING INTRAOCULAR LENS IN INJECTOR ASSEMBLY
    Publication number: 20220151771
    Abstract: A shuttle, vial and injector are provided for storing and presenting an IOL to a patient. The shuttle includes operably engaged shuttle plates having a set of confronting surfaces that flex about a flexure interface between a storage configuration, with at least an optic of an IOL in a nominal state and a loading configuration, with at least an optic of an IOL in a deformed state. The vial engages the shuttle and maintains the shuttle in the storage configuration. The injector receives the shuttle from the vial and includes surfaces for flexing the portions of the shuttle plates to the loading configuration upon engagement with the injector, wherein the shuttle plates impart a predetermined curvature to at least a portion of the IOL.
